OpenDevEd has been streaming our Google Docs / Sheets / Slides workflows for many years, going back almost until the initial launch of apps script. For more details about all our Add-ons, see Our Tools.
BZotero for Docs and BZotero for Slides used to function as independent plugins but, on the new update, they have merged into one app, called bZotero. It allows Zotero links to be embedded into Google Docs and Google Slides that point to a site built with Kerko app.
This plugin needs to be used in conjunction with the Zotero plugin available here: https://github.com/OpenDevEd/zotero-plugin-kerko.
For details, visit our GitHub repository here google-apps-script/repositories, and select BZotero
